People holding Iranian rials, including Iranians themselves, can't seem to get rid of them fast enough. The value of the currency has continued its drop, plummeting 40% against the dollar in the last week alone, reports the New York Times. Mahmoud Ahmadinejad blames "psychological pressures" brought on by Western sanctions, but his political rivals say his government's mismanagement is mostly to blame, and they may rub it in by forcing him to submit to questioning by lawmakers, reports the AP.

"Are these (currency) fluctuations because of economic problems? The answer is no," said Ahmadinejad. "Is this because of government policies? Never. ... It's due to psychological pressures. It's a psychological battle." Meanwhile, Business Insider take a look at "why everyone and their mothers are buying" a different currency: the Mexican peso, thanks to steady industrial growth.

Hilarious! hahahaaha 60% think so Yeah it's real funny that the average citizen in Iran can't afford food, fuel, clothing, or medication. It's their fault that the government is pursing nuclear energy. It's so much worse for Iran to possibly have one 1940's style atomic bomb in a couple years, than it is for Pakistan to have 300 modern nuclear weapons with high tech delivery systems all while they're facilities are surrounded by extremist islamic groups. Maybe if the US military, and NATO didn't show a pattern of only invading countries that didn't have nuclear weapons, then Iran wouldn't try to make one.
